NAME
       pal2rgb - convert a palette color TIFF image to a full color image

SYNOPSIS
       pal2rgb [options] input.tif output.tif

DESCRIPTION
       pal2rgb	converts  a  palette color TIFF image to a full color image by
       applying the colormap of the palette image to each sample to generate a
       full color RGB image.

OPTIONS
   Input Data Options
       The following input data options are supported:

       -C	       Override	 the  default behavior of pal2rgb to determine
		       whether or not colormap entries contain 16-bit or 8-bit
		       values. By default, the colormap is inspected and if no
		       colormap entry greater than 255 is found, the  colormap
		       is assumed to have only 8-bit values. Otherwise, 16-bit
		       values, as required  by	the  TIFF  specification,  are
		       assumed.	 The -C option can be used to explicitly spec‐
		       ify the number of bits for colormap entries: -C	8  for
		       8-bit values, -C 16 for 16-bit values.

   Output File Options
       The following output file options are supported:

       -c	       Specify	a compression scheme to use when writing image
		       data:

		       -c lzw		       Lempel-Ziv and Welch algorithm.

		       -c none		       No compression.

		       -c packbits	       PackBits compression algorithm.

		       -c zip		       Deflate compression algorithm.

		       If no  compression-related  option  is  specified,  the
		       input-file compression algorithm is used.

       -p	       Explicitly  select  the	planar	configuration  used to
		       organize data samples in the output image:

		       -p contig	       Samples	are  packed   contigu‐
					       ously. This is the default.

		       -p separate	       Samples are stored separately.

       -r	       Write  data  with a specified number of rows per strip.
		       By default, the number of rows per strip is selected so
		       that each strip is approximately 8 kilobytes.

OPERANDS
       The following operands are supported:

       input.tif       The name of the input TIFF file.

       output.tif      The name of the output file.
